Invitation to tender for the development of a Cost-effectiveness study on community health workers Terms of reference Background The World Health Report 2006 (1) highlighted a global health worker shortfall of over 4.2 million. Community health workers (CHWs) can play an important part in finding solutions to this problem as they are selected from the communities that they serve, often in remote regions, to improve the equitable access to the national health system. The Kampala Declaration and Agenda for Global Action (2) was based upon the acknowledgment of the critical shortage of human resources for health (HRH), and recognised that CHWs can represent a key element in formulating a strategy to address this challenge. Within that context, the Global Health Workforce Alliance (GHWA) Secretariat has noted that cost-effectiveness information on CHW programmes is often requested by member states and other organizations, in the pursuit of providing evidence to inform key decision makers that have the ability to mobilize and strengthen Human Resources for Health (HRH). It has been recognised that there is currently a significant knowledge gap in peer reviewed and grey literature concerning the cost effectiveness of CHW programmes. A review by Lehmann and Sanders entitled Community health workers: What we know about them (3) commented on the limited studies concerning cost effectiveness of CHW programmes. Similarly, a systematic review commissioned by GHWA on the global experience of community health workers for MDG progress (4) concluded that: further systematic reviews are required on factors affecting the sustainability of CHW interventions when scaled up; the effectiveness of different approaches to ensure program sustainability; and the cost-effectiveness of CHW interventions for different health issues. To address this gap, this research will examine the cost-effectiveness of CHWs, based on the experiences of countries which have implemented CHW programmes at scale, from different global geographic regions and from diverse socio-economic environments. This new research will be a significant step in addressing the knowledge gap and providing invaluable information to policy makers concerning the cost effectiveness of CHW programmes. Objective and research questions The overall purpose of the research study is to build on the available evidence of CHW costs and effectiveness to determine the relative cost-effectiveness of alternative CHW programmes, and the most efficient, feasible and sustainable models of CHW practices as part of national health strategies. The analysis is expected to answer the following specific research questions:
1. What is the evidence on cost-effectiveness of various models and paradigms of CHWs in various countries around the globe which CHW programmes have been implemented at scale? 2. What is the relative cost-effectiveness of different models of service provision (CHWs compared to other cadres of health workers, or combination of cadres involving also CHWs vs. no CHWs) in delivering similar essential health services in different settings? 3. Considering the evidence base for different packages of care that can be delivered at the community level and information on cost and effectiveness of CHWs, what are the options for maximizing delivery of effective health care at the community level? In particular, is it possible to identify key elements of CHW training and support programmes which contribute to or are pre-condition for their cost-effectiveness (for example, on-going supervision or minimum entry qualifications, etc)? Is it possible to document and quantify impact of these factors on cost-effectiveness? 4. From the cost effectiveness analysis, what key messages can be derived for policymakers and partners to inform decision-making on investment and scaling up CHW programmes in order to ensure maximum impact when effectively integrating and embedding CHWs within health systems? Scope of work and approach The GHWA Secretariat will identify, through a competitive tendering process, a suitable institution for the delivery of this task. The GHWA Secretariat has also convened a research committee to advise on the institution selection process, and to review the drafts of the report and cost-effectiveness model produced by the institution. The institution contracted will report directly to the GHWA Secretariat. The following approach will be adopted in the delivery of this task: 1) A review of the literature on the costs, effectiveness and cost-effectiveness of CHW programmes, by type of provider rendering health services. 2) Collection of required secondary data from identified countries that is not available online. 3) Development of a a model to estimate the incremental cost-effectiveness of different models of CHW-based care for different packages of interventions compared with models of care rendered by other providers (doctors, nurses), including sensitivity analysis to test the different scenarios and assumptions. This approach may need to consider both the CEA for the same types of services by different cadres (CHWs vs. other cadres), and for different service modalities that produce comparable outcomes, e.g. number of patients treated or cured.
1) A review of the literature on the cost and effectiveness of CHW A literature search will be conducted in order to identify relevant literature on CHW costs, effectiveness and cost-effectiveness. The literature review will also help to identify key data elements required (e.g. separate cost and effectiveness data) to build the CE model. This will include the identification from the literature of key elements of CHW training and support programmes which contribute to or are pre-condition for their cost-effectiveness. It is envisaged that effectiveness data will be available in the literature, but costing data might have to be obtained. 2) Collection of secondary data from identified countries that is not available online. Secondary data on cost and complementary data on effectiveness and design/ structure of CHW programmes, as well as other cadres for comparison, will be collected from the selected countries (it is envisaged that at least 3 country-specific data gathering processes will have to be undertaken, reflecting different socio-economic contexts). The collection of data will be through interaction with the Ministries of Health and/or academic institutions in the selected countries. Contact persons will be identified by the selected institution within the countries. In collaboration with the contact persons, a questionnaire may be developed to collect the secondary data on the evidence gap in these countries. Collection of evidence and data through the literature and from country informants will enable to determine: CHW effectiveness: CHW programme cost data, including an assessment of the costs involved in the country establishing and sustaining its CHW programme. Outcomes: - Comparisons between CHW programme costs and added value/effectiveness compared to other cadres. - Identification of the most cost effective CHW programmes and approaches. 3) Development of an economic model An economic model will be developed based on the data gathered through the literature review and the country questionnaires, through economic modeling techniques, creating different scenarios and conducting sensitivity testing on costeffectiveness under alternative scenarios of cost and effectiveness, packages of care, personnel cadre and supportive interventions. Country data will have to be from at least 3 different countries, representing different realities in terms of their socio-economic situation, burden of disease, severity of HRH challenges. The scenario and sensitivity analysis will assess under what circumstances CHWs represent the most cost-effective option. The detailed research methodology will have to be presented as part of the tender submitted by the bidders, and may be further defined in consultation with the project committee. The draft research findings, results and recommendations will be presented at the 3rd Global Forum on Human Resources for Health, planned in November 2013 in Brazil, for validation and discussion, and will be presented in the subsequent months to
the partners and countries to inform policy decisions and strategic investment concerning CHWs programmes and CHW components of national health and HRH strategies.
